These are essential because they cover the needed material in a variety of predictable ways. Yes that sounds a little contradictory, but let me explain:
* Students even in K/1 can work on these on their own after modeling only a few times.
* you can add it to a word work station to have them complete independently
* They cover a variety of skills including: vowels/consonants, writing, differentiating the word, using it in a simple sentence!
